Hist. Forms: 1 swuluncg, sulung (rare sulong), Domesday Bk. solin, 2 solling, (also 7 Hist.) swuling, (also 9 Hist.) swilling, 23 (also 79 Hist.) sulling, suling, 4 swol(l)ing, -yng, swyling, suyling, 45 swylling, 9 Hist. sullung. [OE. swulung, sulung, probably vbl. sb. of an unrecorded vb. *swul(h)ian, *sul(h)ian to plough, f. *swulh, sulh plough, SULLOW. The generally accepted view that sulung is f. sulh + lang, long long (Sweet, in Anglia, III. 151) and that it is therefore parallel to furlong (f. furh furrow + long) cannot be maintained in face of the divergent form-history and meaning of the two words.] In Kent, the fiscal unit corresponding to the hide (see HIDE sb.2) and the carucata (see CARUCATE) of other counties.
